An Overview of Centrifugal Fans and Blowers
Do you have an industrial workspace with little-to-no natural ventilation, but you need that area to have “moving” air? If so, a centrifugal fan/blower is ideal. Typically attached to a duct system, it’s ideal for larger spaces, and helps move air or other gases.
A centrifugal fan is made up of a motor, a fan blade and an enclosure. Motors may be big or small. The blade will have a certain shape depending on the fan’s specific application. Notably, the direction of rotation is customizable, too.
Basically, a centrifugal fan/blower has a motor which rotates a fan blade. This, in turn, creates both a low and high pressure area while adding kinetic energy to the air. At the center of the fan there’s low pressure, which creates a vacuum drawing air into the fan. That air flow then flows to the outside edges (toward the high pressure area) and ultimately flows out of the unit’s enclosure in the desired direction.
You’re likely to find centrifugal fans and blowers being used with/for HVAC systems, filtration, drying, eliminating dust, filtering and exhaust, etc.
Types of Centrifugal Fans
There are several types of centrifugal fans/blowers available today. They’re used for a variety of purposes, too, from chemical processing to fume control.
- If you need a fan for clean air handling, you’ll want a centrifugal fan/blower. It can remove and/or refresh air to keep a room “clean.” For light dust loading purposes, particles can be captured, collected and conveyed through various parts of the fan system. Hoods, ductwork, and traps help accomplish this in order to improve air quality and keep a workspace safe.
- Some centrifugal fans are able to process bigger particles than dust– particles such as sand, sawdust, wood chips, grain and pet food.
- What about “saturated air fans?” These centrifugal fans are used when there’s moisture from humidity and/or various gasses in the air and may be made from stainless steel and/or incorporate epoxy coatings to resist moisture.
- If you need a fan/blower for your industrial furnace, oven, and/or heat treating in general, specially designed centrifugal fans/blowers will do the job.
- In order to accomplish the movement of air/gasses, centrifugal fan/blower types include airfoil, forward curved impellers, backward inclined impellers or flat paddle wheel style impellers. Other types include high pressure, industrial exhaust, and radial designs. Ultimately, the customizable design depends on airflow type, speed, static pressure and air quality.
The Benefits of Centrifugal Fans
Centrifugal fans/blowers create high pressure and move air and gasses where needed. With enclosed parts and the ability to reduce/collect particles, they’re ideal for use in systems dealing with air pollution.
Some of the benefits of utilizing centrifugal fans and blowers in various applications include high energy efficiency, excellent durability (even in corrosive/erosive environments), top notch versatility (able to process different air flow conditions), easy maintenance, and the ability to restrict overloading in case capacity is exceeded. Plus, fans are customizable, such that they can be made to fit tight spaces and/or work well in difficult to reach areas.
